1. A euphemism combined with a metaphor: Knob: euphemism for dick head, penis (cf. "get my knob polished"). Slobber: visible pre-cum (pre-ejaculate fluid) emanating from the penis, so called because the fluid is clear and visually resembles drool or spittle.
2. By extension, knob slobber can also mean a dick head bearing visible saliva (spittle) from fellatio, together with pre-ejaculate. The combination of the two is also clear.
A related term is knob slob, a giver of messy blowjobs.
--"Timm pre-cums so much his knob slobber looks like a deluge."

A paraprosdokian is a figure of speech in which the latter part of a sentence or phrase is surprising or unexpected in a way that causes the reader or listener to reframe or reinterpret the first part. It is frequently used for humorous or dramatic effect, sometimes producing an anticlimax . . . sometimes a very funny turn of phrase.
So what's a "paraprosdokian"?
"Like this: I asked God for a bike, but I know God doesn't work that way. So I stole a bike and asked for forgiveness."
"I don't get it"-
"Okay, how about: Do not argue with an idiot. He will drag you down to his level and beat you with experience."
"You mean, something like: I want to die peacefully in my sleep, like my grandfather. Not screaming and yelling like the passengers in his car."
"Phrasemaker!"
